Abstract

Eragrostis, the largest genus in tribe Eragrostideae has 36 species in India and with 406 species in the world. The present study investigates the morphological and micromorphological variations of lemma and palea in nine species of the Eragrostis, collected from Panchmahal and Dahod districts of Gujarat. Qualitative and quantitative features of microharis, and epidermal cells in the different regions, apex middle and base of lemma and palae has been observed. Apart from this, undulation patterns also play a key role in species identification. Two major types of undulation pattern ∩ and Ω have been observed in the studied species. The present study concludes that, different types of microhairs, size and shape of epidermal cells and its undulating pattern can be significantly used in delimitation of Eragrostis with the help of all the qualitative and qualitative characteristic features it was possible to prepare a dichotomous key to identify the nine different species of Eragrostis.
